The Best and Weakest Pre-Washes Ranked (13 Products)

FromDetailing Dogma5/11/2026

Detailing Dogma just covered a deep dive into car pre-washes, testing 13 different products on real, dirty vehicles to see which ones actually cut through the grime. The list is pretty wild, featuring everything from Koch Chemie Gentle Snow Foam and Gyeon Foam to specialized gear like the iK Multi Pro 2 sprayer and MTM Hydro pressure washer components. It’s interesting to see how they used a pH tester to analyze these formulas, along with lab cylinders for precise mixing. They didn't just stick to soaps either; the video includes details on hoses, foam cannons, and even a pocket pH tester to keep the whole process scientific.
